So what do you consider to be the/an appropriate answer to this question?
This seems like a case where "why do we use it," an "how do we use it correctly" are obvious but the definition of what it actually is is a complexity we covered once in freshman statistics and never needed again.
You don't hire a telemarketer by asking them "what is a telephone" you hire them by making sure they know how to use one correctly.
